>>109663503It's worth watching because it has some good segments. Don't expect it to be as good as Avatar, though. Quick rundown:
>Season 1The worst of the bunch, has the most retarded Deus Ex machina ending (because the writers didn't know they'd be allowed to make more seasons so they wrapped the story up incredibly quickly), has the best antagonist in the series, also has a shitty love triangle that takes up too much time and some obvious plot "twists". It's only worth watching so that you get an introduction to the characters and its world which the other seasons build on.
>Season 2Has god tier comedy scenes with a certain character (won't spoil who it is, you'll know when you see him), but outside of that the plot is pretty stupid, the finale as well, although there's a few good fighting scenes and the helicopter scene in the finale is pretty good.
>Season 3Definitely the best season, it has a lot of great fights and moments, a shame that the villain is a cringy anarchist because he is pretty promising at first.
>Season 4The god tier comedy character returns and his scenes are still great, also the first few episodes before Korra gets her powers back is pretty cool as well, but outside of that and a few good fight scenes there's not much good to be had, I especially think the mecha battle is distasteful.
To sum it all up:
3 >>> 4 >>> 2 >>> 1
